Hi All, I am attempting a MB A1181 logic board repair. Problem is the unit will not power up. At this time I have external supply ( bench power supply unit )connected, and get NO battery charging, and No power button functions. When connected the board takes 0.05 Amps if I short the board pwr btn pads I get No signs of life on the screen, speakers etc. I have all drives etc disconnected. However the board now takes 0.35 Amps also the GPU CPU and other devices warm up. I am at this point thinking I have lost a voltage supply somewhere.Anyone been there done that, or anyone interested in helping with this project ?
